In July 2009 the U.S. Virgin Islands enacted legislation creating Act 7075. This legislation requires that all new developments and substantial building modifications install energy efficient solar water heaters to provide at least 70% of the building's water heating needs. This is for all building types: residential, commercial and governmental.
The Department of Planning and Natural Resources may provide a waiver if a significant cost burden is shown. The Department will verify compliance with this requirement at the time development, construction and/or building permits are reviewed.
